A value σ=3, 5±1 is obtained for the spin cut off coefficient in the Fermi gas level density formula from a comparison of calculated and experimental (n, gamma)-intensities feeding the observed levels of deformed nuclei in the rare earths region. The model used for the computations is tested at two nuclei with compound states of low spin (I c =1/2) and high spin (I c =13/2 or 15/2). The calculations can help to determine spins of nuclear levels in some cases.
